identifier uniqueness

But since there is no way to ensure that an identifier is globally

stable, the static description is not stable.
Current identifiers are not globally unique either. www.<foo>.com
where it is implemented as a set of servers behind a load balancer
is a trivial counter-example.

So I submit that we don't need "globally unique" identifiers". We do need
"probabilistically unique" identifiers with a sufficiently high (<< 1) probability.

This is an *important* point.
